Description

Contact panel

Technical field

The present invention relates to contact panel.

Background technology

Since in the past, in the display unit of bank's terminal (ATM (Automatic Teller Machine)), ticketing machine, Personal Computer, automated office equipment, electronic memo, PDA, mobile phone etc., use contact panel. This contact panel does not hinder picture to show, and is that detection touches sensor where, and representatively contact panel it is well known that capacitance type touch-control panel. Capacitance type touch-control panel is the contact panel that the capacitance variations caught between the finger tip of people and electrode thus detects the position of finger tip, such as, it is well known that contact panel disclosed in patent documentation 1.

As shown in figure 12, contact panel disclosed in described patent documentation 1 is by fitting together two planar bodies 105,106 and form, and described two planar bodies are formed with the electrode 103,104 with predetermined pattern shape respectively on a face of substrate 101,102. The pattern form of electrode 103,104 is the structure that multiple rhombus electrode section 103a, 104a connect into linear respectively, the closure of the rhombus electrode section 103a formed on a substrate 101 is mutually vertical with the closure of the rhombus electrode section 104a formed on another substrate 102, and it is not overlapping to overlook rhombus electrode section upper and lower when seeing. By many metal fines are configured to checker board, thus form each rhombus electrode section.

As shown in figure 13, the contact panel formed as described above becomes to be overlooked the multiple uniform tartan design being made up of many metal fines when seeing and is distributed on the whole region of touch surface, it is possible to prevent the problem that the contact panel sharpness (legibility) of local is bad.

Prior art literature

Patent documentation 1: No. 2011-134311, Japanese Laid-Open Patent Publication

, when described contact panel, when two planar body weight of the electrode being formed with predetermined pattern shape are stacked, the position that there is each electrode produces the problem of deviation. That is, as represented with arrow in Figure 14, producing the intensive region of thin grid and not be formed with the region of grid, the homogeneity of tartan design is destroyed, thus causes the problem that the sharpness producing contact panel worsens.In addition, when the contact panel creating the deviation of such position is configured in the display unit of ticketing machine, Personal Computer etc., can produce in the intensive region of thin grid because of the density of electrode cause deep or light. In order to prevent this kind of situation, as long as although the position precision (Anawgy accuracy) when improving laminating two planar bodies is just passable, but the live width thin (such as 15 ��m) due to the metal fine forming electrode, so in fact very difficult not produce position deviation two planar bodies of fitting.

In addition, such as when forming the electrode on substrate by printing technologies such as such as silk screen printings, during drying process after printing, substrate shrinks, because of various reasons such as the material of substrate, gas epidemic disaster, the thickness forming the metal fine of electrode and width, the long side direction of electrode and the length of short side direction, when drying, the degree of the contraction of substrate can change, thus the control shunk is very difficult. In addition, owing to the respective electrode long side direction of planar body of laminating is mutually vertical, so in each electrode formed respectively on a planar body and another planar body, the region that the impact that substrate shrinks significantly produces is different, even if therefore fitting two planar bodies with very high position precision, also there is following problems: be difficult to make to overlook when seeing between the electrode (rhombus electrode section) being formed on each planar body of laminating not overlapping, and be difficult to uniform tartan design is distributed on the whole region of touch surface. Namely, even if fitting two planar bodies to manufacture contact panel with high position precision, also can produce the deviation of tartan design as shown in Figure 14, cause the region producing the intensive region of thin grid shown in arrow and not forming grid, thus cause the sharpness of generation contact panel bad.

In addition, particularly when manufacturing large-scale contact panel, owing to the shrinkage of substrate is big, so it is big with the position departure degree change of the electrode being formed on another substrate to form electrode on one substrate, the sharpness of grievous injury contact panel.

Summary of the invention

In view of described problem, it is an object of the invention to provide a kind of contact panel, it does not rely on the bonding position precision between the substrate being formed with electrode, and the impact do not shunk by substrate, there is excellent sharpness.

In order to reach described object, the present invention provides a kind of contact panel, comprising: insulation layer, multiple first electrode, is configured in the side, a face of described insulation layer, and multiple 2nd electrode, it is configured in another side, face of described insulation layer, first electrode described in each mutually to be formed in the way of same general direction extension, 2nd electrode described in each mutually to be formed along the direction different from the direction that described first electrode extends in the way of same general direction extension, first electrode described in each and the 2nd electrode described in each are the broken line shape electrode wires with multiple point of inflection, when the interior angle of any point of inflection of described first electrode setting broken line shape is as �� 1, and when setting the interior angle of any point of inflection of described 2nd electrode of broken line shape as �� 2, meet following mathematical expression: �� 1-(180 �� of-�� 2) > 10 ��, and the grid different with the shape that described 2nd electrode is formed by described first electrode is dispersed in whole touch location detection region.

The pattern form of multiple 2nd electrodes that the pattern form of multiple first electrodes that the contact panel with described structure can make first surface shape body have and the 2nd planar body have is separate shape, and when by multiple first electrode and multiple 2nd electrode overlap, it is possible to make the tartan design being formed in touch surface configure in the way of the grid of all size and shape substantially evenly disperses on the whole region of touch surface.Therefore, when substrate is formed electrode (such as first electrode) of a side, without the need to considering the forming position of the electrode (such as the 2nd electrode) of the opposing party of formation on another substrate, the electrode (such as the 2nd electrode) of the opposing party can be formed unrelatedly with the forming position of the electrode (such as the first electrode) of a side, so without the need to the overlapping first planar body of high Anawgy accuracy and the 2nd planar body. , it is possible to relax the requirement of the first electrode and the Anawgy accuracy of the 2nd electrode, namely such that it is able to easily make contact panel. In addition, configured in the way of the grid of all size and shape substantially evenly disperses on the whole region of touch surface by the tartan design that multiple first electrode and multiple 2nd electrode group overlap are formed, so the intensive region of the thin grid in local can not be produced and do not form the region of grid, when macroscopic view sees touch surface, it can be seen that uniform tartan design is distributed on the whole region of touch surface substantially.

In addition, when above forming the first electrode and the 2nd electrode by silk screen print method at each substrate (first substrate and second substrate), although first substrate and the problem of second substrate contraction can be produced, even if but occur such substrate to shrink, in the contact panel of the present invention, the tartan design being made up of the first electrode and the 2nd electrode configures in the way of the grid of all size and shape substantially evenly disperses on the whole region of touch surface, even if so cause the size and shape of each grid being distributed different from the size and shape of imagination during design because of the contraction of each substrate, also can not produce to cause the impact that the sharpness making contact panel worsens. that is, even if when each substrate creates contraction, the contact panel of the present invention can also keep excellent sharpness.

In addition, in described contact panel, it is preferred that described first electrode and described 2nd electrode are the broken line shape electrode wires respectively with same period and same-amplitude. When having this structure, for the tartan design of the electrode by multiple first electrode and multiple 2nd electrode overlap are formed, owing to each grid in the whole region being distributed in touch surface can be set to shape and the size of same degree substantially, it is possible to make the sharpness of contact panel excellent.

In addition, the relational expression shown in described mathematical expression is met by being set to by �� 1 and �� 2, form the arbitrary part angular cross to specify inevitable with the arbitrary part of the electrode wires forming the 2nd electrode of the electrode wires of the first electrode, so on the whole region of the touch surface of contact panel, the tartan design of regulation can be made substantially to be uniformly distributed, such that it is able to more effectively prevent local from producing the intensive region of tartan design.

It is also preferred that, the interior angle of each point of inflection of described first electrode and described 2nd electrode is all more than 90 ��. When the electrode wires being all more than 90 �� by the interior angle of each point of inflection is formed, the intersection point of the first electrode and the 2nd electrode becomes few, it is possible to make the sharpness of contact panel better.

It is also preferred that, the pattern form of multiple described first electrode and described 2nd electrode has single electrode wires width and the repeat patterns of electrode wires spacing respectively. By having this structure, for the tartan design of the electrode by multiple first electrode and multiple 2nd electrode overlap are formed, the shape of each grid on the whole region being distributed in touch surface can be set to more identical degree with size, it is possible to make the sharpness of contact panel better.

In the contact panel 100 with above structure, the detection method of touch location is identical with conventional capacitance type touch-control panel 100, if with the optional position of the face side of finger touch first planar body 1, then the first electrode 12a is contacting the electric capacity ground connection of position by human body with the 2nd electrode 22a, flow through the first electrode 12a and the current value of the 2nd electrode 22a by detection, thus calculate the coordinate of contact position.

The first electrode group 12 that first planar body 1 of the overlap of the contact panel 100 of the present invention and the 2nd planar body 2 have respectively and the 2nd electrode group 22 are the aggregates of the broken line shape electrode wires with multiple point of inflection K, therefore the pattern form of the 2nd electrode group 22 (multiple 2nd electrode 22a) that the pattern form of the first electrode group 12 (multiple first electrode 12a) that first surface shape body 1 has and the 2nd planar body 2 have can be made, form separate shape, and when the first electrode group 12 and the 2nd electrode group 22 overlap, the grid that the tartan design formed in touch surface can be made to be configured to all size and shape is dispersed on the whole region of touch surface substantially. like this, when substrate is formed electrode (such as the first electrode 12a) of a side, the forming position of the electrode (such as the 2nd electrode 22a) of the opposing party formed on another substrate need not be considered, the electrode (such as the 2nd electrode 22a) of the opposing party can be formed unrelatedly with the forming position of the electrode (such as the first electrode 12a) of a side, so without the need to making the first planar body 1 and the 2nd planar body 2 overlapping by high Anawgy accuracy. , it is possible to relax the requirement of the first electrode 12a and the Anawgy accuracy of the 2nd electrode 22a, namely such that it is able to easily make contact panel 100.In addition, the grid that the tartan design overlapped by the first electrode group 12 and the 2nd electrode group 22 becomes all size and shape is evenly distributed on the whole region of touch surface substantially, so the intensive region of the thin grid in local can not be produced and do not form the region of grid, macroscopic view sees touch surface, it can be seen that uniform tartan design is distributed on the whole region of touch surface substantially.

In addition, when burning till after each substrate (first substrate 11 and second substrate 21) upper formation the first electrode 12a and the 2nd electrode 22a, first substrate 11 and the problem of second substrate 21 contraction can be produced. , even if there occurs the contraction of such substrate (first substrate 11 and second substrate 21), in the contact panel 100 of the present invention, the grid that tartan design because being made up of the first electrode 12a and the 2nd electrode 22a becomes all size and shape is evenly distributed on the whole region of touch surface substantially, so because of substrate (first substrate 11 and second substrate 21) though contraction cause the size and shape of each grid being distributed from design time imagination size and shape different, also can not produce to cause the impact that the sharpness of contact panel 100 is worsened. that is, even if when substrate (first substrate 11 and second substrate 21) creates contraction, it is also possible to keep the good sharpness of contact panel. in addition, in this contact panel 100, owing to sharpness can not be impacted by the contraction of substrate (first substrate 11 and second substrate 21), so when forming each electrode 12a, 22a by print processes such as silk screen print methods respectively on each substrate 11,21, also the contraction of each substrate 11,21 need not be considered, thus the manufacture making the first planar body 1 and the 2nd planar body 2 becomes easy.

In addition, in display unit contact panel 100 being configured in ticketing machine or Personal Computer etc., the reason of the structure condition (size of black matrix, the size of RGB pattern and arrangement direction etc.) of the colored filter having due to display unit, imagination also has the situation producing ripple, but by so simple methods such as the interior angle of each point of inflection K of adjustment (change) first electrode 12a and the 2nd electrode 22a and spacing, so that it may produce ripple to suppress.

In addition, in the contact panel 100 of the present invention, the first electrode 12a and the 2nd electrode 22a is made up of the broken line shape electrode wires with same period and same-amplitude respectively. Therefore, for the tartan design of the electrode by multiple first electrode 12a and multiple 2nd electrode 22a overlap are formed, owing to each grid on the whole region being distributed in touch surface can be set as shape and the size of same degree substantially, it is possible to make the sharpness of contact panel 100 excellent.

In addition, owing to the pattern form of multiple first electrode 12a and the 2nd electrode 22a is formed by the repeat patterns with single electrode wires width and electrode wires spacing respectively, so the shape of each grid on the whole region being distributed in touch surface can be set to more identical degree (be set to evenly) with size, such that it is able to the sharpness making contact panel 100 is better.

In addition, it is possible to so that the electrode wires spacing forming each first electrode 12a of the first electrode group 12 is different from the electrode wires spacing of each 2nd electrode 22a forming the 2nd electrode group 22. When having this structure, in the tartan design of the electrode being made up of multiple first electrode 12a and multiple 2nd electrode 22a, owing to can more effectively suppress local to produce the intensive region of thin grid, it is possible to make the sharpness of contact panel 100 excellent.

At this, the present inventor has made the first planar body 1 of contact panel 100 and the sample A��F of the 2nd planar body 2 that form the present invention, when each sample is configured on a monitor with two overlapping states, sharpness having been carried out sensory test, this content of the test and result are as follows.

Content of the test is the following shown sample A��F of each preparation two respectively, in the way of the direction making broken line shape electrode wires extend becomes orthogonal direction, two samples is overlapped on a monitor, has judged the quality of sharpness in this case with range estimation. About the combination of overlap, such as, sample A and sample A combined, sample A and sample B is combined, by sample A and sample C in combination, like this sample combination of all categories, judged the quality of sharpness.

Sample A to be the interior angle (�� 2 in the �� 1 being equivalent in (a) of Fig. 7 or (b) of Fig. 7) of each point of inflection K be 90 ��, the broken line shape electrode wires of the cycle, to be 2.742mm, amplitude be 1.371mm, is arranged with multiple with electrode wires spacing 0.429mm. Sample B is the broken line shape electrode wires identical with sample A, is arranged with multiple with electrode wires spacing 0.527mm. Sample C is the broken line shape electrode wires identical with sample A, is arranged with multiple with electrode wires spacing 0.686mm. In addition, sample D to be the interior angle (�� 2 in the �� 1 being equivalent in (a) of Fig. 7 or (b) of Fig. 7) of each point of inflection K be 136 ��, the broken line shape electrode wires of the cycle, to be 6.856mm, amplitude be 1.371mm, is arranged with multiple with electrode wires spacing 0.429mm. Sample E is the broken line shape electrode wires identical with sample D, is arranged with multiple with electrode wires spacing 0.527mm. Sample F is the broken line shape electrode wires identical with sample D, is arranged with multiple with electrode wires spacing 0.686mm.

In addition, in order to compare, each electrode wires preparing two formations and there is the sinusoidal waveform of specified period and regulation amplitude, and by the electrode wires spacing multiple sample a��f that be arranged in substrate on of this electrode wires to specify, and in the way of the direction making the electrode wires of sine wave shape extend becomes orthogonal direction, two samples are overlapped on a monitor, judged the quality of the sharpness in this situation with range estimation. About the combination of overlap, identical with the situation of sample A��F, the sample of all categories is combined. At this, sample a to be the cycle be 6.856mm, amplitude are the electrode wires of the sinusoidal waveform of 1.159mm, are arranged with multiple with electrode wires spacing 0.429mm. Sample b is the electrode wires of the sinusoidal waveform identical with sample a, is arranged with multiple with electrode wires spacing 0.527mm. Sample c is the electrode wires of the sinusoidal waveform identical with sample a, is arranged with multiple with electrode wires spacing 0.686mm. In addition, sample d to be the cycle be 6.856mm, amplitude are the electrode wires of the sinusoidal waveform of 1.489mm, are arranged with multiple with electrode wires spacing 0.429mm. Sample e is the electrode wires of the sinusoidal waveform identical with sample d, is arranged with multiple with electrode wires spacing 0.527mm. Sample f is the electrode wires of the sinusoidal waveform identical with sample d, is arranged with multiple with electrode wires spacing 0.686mm.

When sample a��f combining and configuring that the electrode wires of sinusoidal waveform is formed on a monitor, the result obtained is: in whole combinations, produces ripple near the electrode of the electrode wires of sinusoidal waveform, and sharpness is not good. On the other hand, for sample A��F that the broken line shape electrode wires with multiple point of inflection K is formed, the result obtained is: not having the ripple producing to confirm in sample a��f, sharpness is more excellent.In addition, between sample A, between sample B, between sample C when combination, the result obtained is: the bright spot creating spot shape, and sharpness is slightly poor.

In addition, distinguished, particularly in the situation that sample B and sample E are combined and when sample C and sample E is combined, it does not have produce bleeding and the outstanding phenomenon of electrode wires pattern, it is possible to obtain extraordinary sharpness. At this, in sample B, sample C and sample E, the interior angle defining each point of inflection K all broken line shape electrode wires more than 90 ��. Therefore, think by make the interior angle of each point of inflection K of the first electrode 12a and the 2nd electrode 22a of this contact panel of formation 100 be formed electrode wires as the mode of more than 90 ��, it is possible to obtain not easily producing ripple, bright spot, bleeding etc. and not easily producing the outstanding contact panel 100 of electrode pattern. In addition, when forming the first electrode 12a and the 2nd electrode 22a by the electrode wires of the interior angle of each point of inflection more than 90 ��, the intersection point of the first electrode 12a and the 2nd electrode 22a becomes few, it is possible to make the sharpness of contact panel better.
